Why do people like Dr. Laura?

Why is it that people like Dr. Laura so much. I believe it is because people really want to know "the right thing to do" as she puts it. Our culture is starved for moral structure. All people have natural law written in their hearts and yet it has become almost taboo to acknowledge that there is indeed a right and wrong. Most psychologists do not approach the topic at all. It refreshing that Dr. Laura actually focuses on the morality of a situation, and people really appreciate that perspective. After all, it's what really matters.
